    Abstract
    The Present work reports the variability of the derived sound channel and its parameters (surface sound velocity, conjugate depth, SLD (Sonic Layer depth) and SOFAR(Sound Fixing and Ranging) depth) has been presented over the Bay of Bengal and Arabian Sea. We use World Ocean Atlas Annual data (2013) on temperature; salinity of North Indian Ocean (0°–25°N; 50°–95°E) and its bathymetry have been utilized for the present computation. The depth of the sound channel axis increases towards the northern latitudes in the Arabian Sea, while it decreases in the Bay of Bengal. Coming to the conjugate depth, it shows variation from 120-400 m in the Bay of Bengal and 50-320 m in the Arabian Sea. The range of SLD is varying between 20-40 m in the Bay of Bengal and 10-30 m in the Arabian Sea. The Bay of Bengal and the Arabian Sea have depth limited nature of the profile, i.e. surface sound speed exceeds the near bottom values. This has an important implication in the sound propagation in the SOFAR channel. Anticipated acoustic rays in an ocean with depth limited profile will propagate as surface refracted, bottom reflected (RBR) rays. As a result, the effective sound channel lies much below the sea surface
